• Local sheriff described the harassment as among the most disturbing he had dealt with in his career

  Two teenage girls are behind bars following allegations that they carried out a campaign of harassment against a mentally-challenged boy including stabbing him, dragging him by the hair and forcing him to engage in sex acts with an animal.
  The St. Mary’s County Sheriff’s Office said 17-year-old Lauren Bush and an unnaned 15-year-old girl – both students at Chopticon High School in Morganza, Maryland – recorded the assaults against the autistic 16-year-old victim on their cell phones. 
  Footage shows the suspects force the teen to walk on a partially frozen pond, which resulted in him falling through the ice several times.
  Each time, police said, the suspects refused to help the boy out of the frigid water.
  Sheriff Tim Cameron told ABC7 that the allegations leveled against the girls are among the most disturbing he has dealt with in his career. 
  He says that several times between December and February, the suspects preyed on the victim – assaulting him with a knife, kicking him in the groin, dragging him by the hair, coercing him to engage in a sex act with an animal, and forcing him to walk on the partially frozen pond.
  ‘Another video depicts the male on an icy pond being told to continue to walk out further, actually falling in the water several times and pulling himself out,’ said Cameron.
  Bush, who lives in a rural part of the county south of Mechanicsville, knew the victim well, according to investigators
  Both girls are students at Chopticon High School in Morganza, Maryland
  Police say the girls have admitted to videotaping the incidents, but officials are still trying to figure out why.
  ‘Who could harbor this ill will to do something so completely heinous?’ said Cameron. ‘I don’t know. It’s hard to fathom, really.’
  Both girls have been charged with two counts of 1st degree assault, two counts of 2nd degree assault, soliciting subject in the production of child pornography and false imprisonment.
  Bush was charged as an adult. She is being held at the St. Mary’s County Detention Center. The other teen is being detained at the Waxter’s Children’s Center.
